Abstract

An attachment nut includes a base member (1) and an elastic retaining insert (6) connected to the base member. The attachment nut serves for fastening components (18), or pipe members, to a C-shaped profiled rail (15). The retaining insert (6) has locking tabs located diametrically opposite one another. The tabs can be pivoted about an axis into a slot-like opening in the profiled rail (15) to prevent the turning of the attachment nut. Each locking tab has a projecting lug for effecting the manual turning of the attachment nut within the profiled rail (15).

Description

The set screw nut of shaped steel
The present invention relates to a kind of set screw nut, this kind set screw nut has a base and an elastomeric stopper that is connected with base, wherein, and application mechanism that base is strong and the length that portraitlandscape is arranged.
By the set screw nut of the known a kind of the above-mentioned type of US-PS3493025, it is used for member is fixed in the transverse section is the shaped steel of C shape substantially, and two crimps of this kind shaped steel are parallel to each other, and stretch to the inboard of shaped steel.Base is positioned at the inside of shaped steel, can move vertically in the inside of shaped steel in pre-assembled state.The retainer that links together with base is positioned at the outside of shaped steel, and rests on two oral areas that crimp is the notch on boundary with shaped steel.
Base has non-circular external frame, at this moment, and the width that the minimum dimension of its external frame vertically records perpendicular to shaped steel less than notch.(it is the load mechanism of internal thread and the tooth meshing zone that two extend parallel to each other that its form is arranged in the hole also to be provided with central through bore on base, when set screw nut being put into shaped steel and half-twist to its pre-assembled position, the free end co-operation of this tooth meshing zone and crimp.
Retainer has one to be in first district that axial restraint is connected and flexible flange shape second district is arranged with base in central authorities, and this second district is supported on the notch in-scope of shaped steel outer surface.A central through bore is arranged on the retainer, and its diameter diameter with the through-hole diameter of base or fastening screw trip bolt bar basically is identical.This fastening screw trip bolt passes the central through bore of retainer, stretches in the central through bore of base, is used for member is fixed on the shaped steel.
The shortcoming of this known fixed nut is: owing to be difficult for the grasping set screw nut, so, be difficult to set screw nut is turned to pre-assembled position on shaped steel with hand.Another shortcoming is, in tightening the process of fastening screw trip bolt, set screw nut also rotates, and breaks away from pre-assembled position to cause set screw nut, make base no longer with the free end of shaped steel crimp near.
The objective of the invention is to: make a kind of set screw nut, when it is inserted shaped steel, can be easy to rotate by hand; When tightening fastening screw trip bolt, set screw nut is not along with rotation; And this nut can be made economically.
The measure that the present invention takes is: be provided with on retainer along diameter braking plate opposite each other.Braking plate can be around being parallel to the rotating shaft rotation that the base longitudinal length extends, the wide end of braking plate and the lateral length basically identical of base.
Braking plate is arranged on the retainer, and has constituted a grasping area that increases retainer, and it can make people be convenient to use grasped, and thereby is easy to make retainer to rotate with base.When braking plate bent in the notch of shaped steel, it had just constituted safty device that prevent that set screw nut from rotating.
When being put into a member on the shaped steel, automatically change in the notch of shaped steel in order to make braking plate, in a braking plate side of base dorsad, a projection is arranged preferably.This projection protrudes upward that side of base dorsad from retainer, has formed the acting surface of a power, and this power acting surface is convenient to use grasped, and thereby can rotate set screw nut more easily.
In order to make braking plate be easy to rotate, the rotating shaft district retainer that is preferably in retainer has small wall thickness.For this reason, retainer is towards that side of base, processed one along rotating shaft groove longitudinally.
For after being put into member on the shaped steel, can not make retainer become middle bed course between member and shaped steel, preferably with the wall thickness of retainer along base vertically towards free end direction attenuate.This wall thickness is contracted to zero always in this case, and at this moment, this attenuate is to carry out on that side of base on the retainer.This attenuate for example can be harmonious with the oral area of notch, thus constant along whole notch retainer wall thickness, from the outside attenuate gradually of notch.
With reference to the accompanying drawings, represented embodiment is described further the present invention.Accompanying drawing is:
The set screw nut broken section that Fig. 1 has retainer and fits together with shaped steel by the present invention;
The plan view of shaped steel, retainer and base that Fig. 2 is shown in Figure 1, broken section;
Fig. 3 along Fig. 2 III-III line by having retainer base and the sectional view of shaped steel.
In Fig. 1 to Fig. 3, a kind of set screw nut with base 1 and the elastomeric stopper 6 that is connected with base 1 has been described.Base 1 has a non-circular head, one to have the central through bore of internal thread 5 and the tooth mesh regional 2 that two extend parallel to each other.A cylindrical convex shoulder 3 is coaxial with through hole.Axial resilient retainer 6 is contained on this convex shoulder 3.On the cylindrical convex shoulder 3 of base 1, radially Tu Chu convex 4 is used for retainer 6 axial reaching are fixed on base 1 week.Convex 4 may be stuck on the rib 11 of retainer 6.Rib 11 is somes of interior ring 8.In ring 8 be positioned on the same plane around its outer shroud 7.Outer shroud 7 and interior ring 8 are flexibly linked together along diameter cross structure 9 opposite each other by two.Convex 4 and rib 11 are as cross structure 9, and be opposed along diameter each other, but be provided with respect to the cross structure 9 90 ° of ground that stagger.
The wall thickness W of the outer shroud 7 of retainer 6 at least opposite each other along diameter and on free-ended both sides attenuate.Attenuate 10 is designed to retainer 6 top those sides to bare bones 10 are thinned to zero towards those sides away from base 1.
On retainer 6 outer shrouds 7, be connected with two each other equally along the opposed braking plate 13 of diameter.That relative with base 1 from each braking plate 13 side is stretched out a projection 14, and projection 14 can make people be easier to base 1 is rotated with axial resilient retainer 6.A kind of moulding of surface is designed for grasping projection better 14.Be parallel to base 1 longitudinally the width of braking plate 13 less than the width S of shaped steel N notch 20.Braking plate 13 can rotate around the rotating shaft 12 that is parallel to base 1 longitudinal extension.But in order to have turning quality, retainer 6 has a semicircular groove at the position, place of axle 12, and groove is located at outer shroud 7 and faces beyond the base 1.
For example be used for member 18 or pipeline are fixed in the shaped steel 15 of C shape section by set screw nut of the present invention, this shaped steel 15 has a notch that extends longitudinally 20.The width S of notch 20 crimp 16 parallel to each other by two and that bend in the shaped steel is the border.On the free end of crimp 16, be shaped on dentation profile 17, this dentation profile and tooth meshing zone 2 complementations on base.
If the extra wide degree be the base 21 of B with retainer 6, insert in the shaped steel 15 and half-twists by notch 20, then as shown in Figure 1 to Figure 3, set screw nut is in pre-assembled position.Slightly upwards lift braking plate 13 from the oral area of the rounding 3 of notch 20, thus when the rotational fixation nut braking plate 13 along the upper surface slide of shaped steel 15.When rotating, be located on the base 1,2 partly importing inclined-planes contact with the crimp 16 of shaped steel 15 in the tooth meshing zone.By importing the inclined-plane, base 1 and interior ring 8 are removed mutually vertically with respect to the outer shroud 7 of retainer 6.Thus, retainer 6 has been subjected to a prestressing force.If set screw nut is in Fig. 1 to position shown in Figure 3, then the meshing zone 2 of base 1 is meshed with dentation profile 17 on being located at shaped steel N crimp 16.Meanwhile, base 1 moves axially along the opposite direction towards crimp 16, and the amount of the tooth depth of mobile at least dentation profile.In this case, retainer 6 axial compression.
Retainer outer shroud 7 abuts in the oral area of notch 20 with its weakened section, so retainer 6 that side of base 1 dorsad is no more than or only surpasses slightly the upper surface of shaped steel N.
After being contained in set screw nut on the shaped steel N in advance, can shown in Fig. 3 dotted line part, member 18 be placed on the shaped steel 15, at this moment, the stop surface 14a of the projection 14 of retainer 6 contacts with the bottom surface of member 18.The braking plate 13 that has a projection 14 12 is inwardly bent in the notch 20 of shaped steel around the shaft, flushes with the upper surface 15a of shaped steel 15 until stop surface 14a.Can accomplish that by means of braking plate 13 when it screwed for the fixed block 19 of fastening screw trip bolt in form in the internal thread 5 that will be screwed into base 1, set screw nut can not rotate again.
